GUIDE WIRE DEVICE FOR REMOVING SOLID OBJECTS FROM BODY CANALS

摘要

PROBLEM TO BE SOLVED: To provide a vascular filter for capturing and removing emboli.

SOLUTION: The vascular filter for capturing and removing emboli includes a sack 12 having a mouth 14 and a closed bottom 16 opposite the mouth 14. A guide wire 4 is received through the mouth 14 of the sack 12 and projected through the closed bottom 16 of the sack 12. The closed bottom 16 of the sack 12 is connected to the projection of the guide wire 4 therethrough. A collapsible frame 8 is connected between the guide wire 4 and the mouth 14 of the sack 12. The collapsible frame 8 biases the mouth 14 of the sack 12 open around the guide wire 4. A tube 6 slidably receives the guide wire 4 coaxially therein. The collapsible frame 8 is movable via the guide wire 4 between outside the tube 6 where the mouth 14 of the sack 12 is biased open by the collapsible frame 8 and inside the tube 6 where the mouth 14 of the sack 12 is closed.
